Do you know someone who takes their fun very seriously? Calling the CherryMax Hammerhead a sled almost seems unfair—how about a high-velocity gravity-fueled human transport vehicle? The aluminum frame weighs less than ten pounds, which ensures great speed while barreling down the hill and easy lugging on the way back up. The ergonomic mesh seat absorbs bumps, and steering arms help avoid trees. But don't fool yourself into thinking this free-form fun ride is kid stuff. Wear a brain buffer—and never drink and slide.
